Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class StiffnessMatrixAssembler< ELEMENT_DIM, SPACE_DIM >

Simple implementation of AbstractFeVolumeIntegralAssembler which provides the stiffness matrix

K_{ij} = integral_{domain} grad phi_i(x) . grad phi_j(x) dV

where phi_i is the i-th (linear) basis function.
